Can this model connect to my home computer thru the internet and a service like "logmein.com"? Also, Does it have the ability to vibrate to let me know of an appointment I set? Lastly, Where on the internet would I be able to see the owners manual so I would not have to ask so much? I have been to HP's site and the only manual I can find is for wifi instructions. HP live chat will not work until I purchase it and have a ser #.

If your desktop is running Windows XP Pro, you can use Terminal Services on the iPAQ to remotely connect to the PC. If not, there's also a product called GoToMyPC.

That iPAQ model can put a message on screen, flash the LED and play a sound to notify you of appointments. It does not have vibrating alerts (not many PDAs have this feature which is more common on phones).
